Application filed November 2:, 192a. Serial 801671251 To all wlmm it may concern:

Be it known that I, ALBERT B. CmssON, a citizen of the United States, and a resident of Geddes, in the county of Onondaga and State of New York, have invented'a certain new and useful Pressing Machine, of which the following is a specification.

This invention relates to pressing ma-.

chines as garment and laundry pressing machines and has for its object a particularly simple and efficient motion transmitting mechanism for controlling the application of heavy pressure bycpower mechanism.

The invention consists in the novel features and in the combination and construetion hereinafter set forth'antl claimed.

' In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

r Figure 1 isa side elevation of a pressing machine embodying my invent-ion,

Figure 2 IS a large sectional plan view line 22, Figure 1 showing the means. for

effecting the connection and disconnection of the power shaft and motion transmitting mechanism.

Figure 3 isa detail view of the cam. Figure 4 is a face view of the latch p ate. Figure 5 is a face view of the pressure member which coacts with the latch plate;

Figure 6 is a fragmentary view of the portion of the manual means for operating the clutch.

This pressing machine comprises generally a pair of coacting pressing elements having relative movement one toward and from the other, the movable element being movable by the operator from the open position toward pressing position, power means for actuating the movable element to apply heavy pressure. after the movable element has been moved by hand toward the other element motion transmitting means between the power means and movable element comprising an intermittently movable cam and a member having a follower'coacting with construction, it having a table 21on which is supported a neck or bracket 3. 4 and 5 The element 4 is usually called the lower buck and is mounted upon the bracket I).

andhead 5 are usually formed hollow and,

are connected in a steam system and either are the pressing elementa the element 5 being movable toward and from the element 4.

one or both may be provided with perforations in the face thereof in which steam can be e ected, if desired, on the articles being pressed.

The press head 5 ishere shown as supported by a lever or'yoke 6, this lever bein pivoted between its ends at 7 to a standar .8 rising from the rear end of the frame 1, the lever having rearward-1y and forwardly extending arms 9',- 10. The press head is car.- 7

ried in any suitable manner by the forward arms 10.

,The power'means preferably comprises a constantly rotating shaft 11, which is connected to a shaft of constantly running motor A on the shaft of which a flywheel B- is mounted. The shaft 11 is in alinement with the motor A and is an extension of the armature shaft of the motor. The shaft 11 is, also, shown as formed with a worm 12 thereon, meshing with the worm gear 13 loosely mounted or mounted to rotateabout a shaft 14. The shafts 11, 14, the worm and worm wheel 12, 13 and the half revolution or periodic clutch, to be presently described,

are to be suitably supportedin a casing 15, supported in any suitable manner by. the frame 1.

. Thefmotion transmitting means between the shaft 11 and the press head 4, in addition'to the ever 6 comprise toggle links 17, v

18 pivoted together at 19 and pivoted respectively at 20, 21 to the rear arm 9 of the lever B and to the lower end frame'l, a member or lever 22 extending forwardly from the link .18, the shaft 14 before mentioned.

an intermittently movable cam 23 mounted on the shaft 14 and a member 24 carried by the lever arm 22 and coacting" with the cam. Y

Thecam 23 or shaft 14 is connected or clutched to the shaft 11 or worm gear 13 rotatab e with the shaft 11 by operator actuated means to be hereinafter described.

A suitable counter weight 25 may be carriedby the rear arm 9 of the lever 6 and the lever 6 at the front end thereof or the press head, 5 is provided with a handle 26 at the lbs i -pris'es a periodic or half revolution clutch having a section 31 cpnnected to the cam 23 front side of the press head by-means of which the. press heae't is moved from open position toward closed osition or preferably to position ,where 1t overlies the gar- 5 ment on the lower buck 4. e v

The cam 23, as here shown, is a'scroll can and the member or lever 24 is provided with afo llower as a roller 27. This member or lever 24, as here shown, is pivoted on for-' to the arm or lever 22 and is provided with laterally extended weighted arm 29, which tends to move the lever 24 on its pivot in such direction as to move the follower 2'? l5 toward the cam or low point of the periph eral cam face thereof when the lever or arm 22 has been moved downwardly by manual closing of the press head, as when the operatorpulls downwardly on the handle 26. The cam 23 is, also, formed with a laterally inclined face extending across the-'pev'ripheral cam face for shifting the follower out of the path' of the peripheral face at a predetermined point in-the rotation [of the 5 cam. The weighted arm 29 normally tends to hold the roller 27 against the end face of the cam. When the press is closed by pulling down on the handle 26, the member 22 moves downwardly and, when the roller 28 comesopposite the low point of the peripheral surface of the cam, the weighted arm moves the roller under the low point of- .the cam, and when the clutch, to be described, is shifted to connect the cam to the co stantly running motor, the cam makes a ha df revplution depressirilg' theh mlember an a in' ressure t rou t e to ge links rid lex er ti to the press head; 61611 the cam has made a half revolution, the periodic clutch shifts to off position automatically and the cam remains engaged with the follower and holds the member 22 depressed and, hence the press headt in pressing position indefinitelyorlong enough 'to suit, the operator.

' again manually, shifts the'periodic clutch whereupon the cam makes another half revo lution and, during such half revolution, the

laterally inclined face 30 thereof moves the I roller out of engagement with the peripheral face of the cam whereu on the counter- 5 weight 25opens the press. t the end' of the second half revolution, theperiodic clutch automatically disconnects itself from the power shaft 11. The manual or operator. operated ineans for controlling the actuation of the cam '23 or controlling the connection of the cam 23 to the power? shaft 1I or worm gear 13 comand a section rotatable with the worm gear 13, and manual means for engaging and disengaging the clutch sections. 'The clutch here shown is adisk clutch and the driven wardly and rearwardly extending axis 28 The@ operator then means section 31 assoriated with the cam 23 comprises a hub keyed to the shaft 14 and a series of disks 33 slidably interlocked or keyed to the hub, and the driving clutch section rotatable with the worm gear 13 comprises disks 35 interleaved with former disks 33 and 'slidablykeyed to arms'36 extending from the worm gear 13 parallel with the shaft 14. The clutch further includes a' pressure ring 37 keyedto the clutch section 31 and presslng against. the disks and a shaft 14 and opposed to the first pressure ring, sprmgs 39 interposed between the pressure rings, a latch plate 40 fixed from rotasecond pressure' ring 38 mounted on' the tion and formed with annular plane surface 41 concentric with the shaft14 and withdiametrically opposite notches or notches 43 coacting with teeth-or rollers 44 on the second pressure ring 38 and" means for shifting the second pressure ring 38 for carrying the rollers 44 out of the notches 43.

As here illustrated, the springs 39 encircle rods or studs 45 projecting from-the first pressure ring 37 and through holes in the second pressure ring 38. The latch plate 40 forms a cover for the casing'15. The con struction per se of the periodic clutch. forms no part of" this invention and any suitable periodicclutch may be used. 7 7

Theshifting means, as here sh'own, com-' prises a hand lever 46 pivoted at 47 to the frame and connected by a link 48 to one arm V of a bell crank lever'49, the other arm of which carries a fork 50 working in a groove '51 in the hub .52 of the second pressure ring 38. Obviously, upon the movement of .the hand lever 46, the second pressure ring 38 will be shifted axially to the left, Figure 2, against the springs 39 andcause. the disks 33, 35 to frictionally engage and the rollers 44 to move out of the notches 43 or the latch plate 40. VV-h'ereupon the cam 23 and the shaft14 will be rotated with the worm wheel 13 and, in so doing, move the teeth or rollers annular face41 of the latch plate 40 until thecam makes a half revolution when the teeth orrollers '44 again come into a-linement with the notches 43 and the second pressure ring 38 is shifted axially by the springs 39, moving the teeth or rollers 44 into the notches 43 and causing the disks 33, 35 to separate or disengage. The cam thus makes engagement with the peripheral face of the '44 ofthe second pressure ring 38 along-the cam 23, so thatthe press head 5 is opened by the counterweight at the, rear end of thc lever6.

' In operation, when the ress is open, the operator closes the press a on the handle 26 and thus causes the lever 6 to move downwardly until the head engages the article on the lower buck 4. During.

such movement, the toggle links 17, 18 are moved toward a straight line, the lever 22 is moved downwardly carryin the member 2% downwardly far enough, so filat the roller 27 is shifted by the weighted arm 29 under the low point of the cam 23. The operator then actuatesthe hand lever 46 thus shifting the second pressure member 38 and the rollers 44 out of the notches 43 and causing the clutch disks 33, to engage whereupon'th'e cam 23 makes a half revolution, causing the head 5 to bebrought down with pressure on I the garment or other article on the lower buck 4, the cam 23 remaining engaged with the cam follower 27, thus holding the pressure head in its pressing position. Vhen pressure has been applied long enough to suit the operator, lie again actuates the handle 46 in the same direction as before, again engaging the clutch disks and causing the cam 23 to make another half revolution and, during this secondhalf revolution, th laterally in.- clined face 30 of the cam pushes the follower 27 out of position to engage the peripheral surface of the cam, so that thecounterweightis free to act and open the press.
